The Update Date on posts never worked

I don’t know since when this bug exists on this website, but basically a post has a created, published and last updated date, and all three are shown on the website at multiple places… but until today, the last updated date was NEVER updated, and since it took the first date at the creation of the post, the published date was always AFTER the last updated… which is totally dumb xD

Now when a post will be updated, the modified date will be set to the time of update
